TEETHOD 0R PROCESS FOR MAKING ROTATABLE TOOL CARRIERS -FOBZPLALNING MACHINES AND THE LIKE.

Application filed March 28, 1921. Serial No. 456,155.

To all whom it may concern Be it known that l, Josnrn W. @Lrvnn, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of lVlichigan, have invented new and useful lmprovements in Methods or Processes-for Making ltotatable Tool Carriers tor Planing Machines and the like, of which the following is a specification.

The present invention relates to methods orprocesses for making rotatable tool-carriers for planing machines and the like; and its object is to provide simple and improved 7 methods or processes for making such toolcarriers.

My methods or processes are hereinaiter set forth, and a tool-carrier made by such processes or methods is illustrated by the accompanying drawings, in which Figure 1 is an end viewof a rotatable toolcarrier for a planing machine;

Figure 2 is a side view of a portion of the same; a

Figure 3 is an end view of a blank used in making pairs of tool-clamping members of such a carrier;

Figure 4- is an end View of such a toolclamping member; and

Figure 5 is an inner side view of the same.

In the tool-carrier chosen for illustration by the drawings and for detailed description in the body of this specification, the elongated body member 1 of the rotatable tool-carrier has formed at its ends means for mounting it rotatably, as the ournals 2. This body member has one or more (two in the construction illustrated) table portions 3, being fiat surfaces on which lie the tools, as the plane bits or irons 4c, and also has adjacent the opposite sides respectively of each such table portion,a1irst recess 5 and a second recess 6, such recesses being continuous grooves or depressions extending in the iongitudinal direction of the body member as shown.

This tool-carrier is made by rolling suitable metal bar or blank lengthwise through a rolling mill, whereby the table portions and the recesses are formed by suitably shaped rollers of the mill. The table-portions are machined or dressed down to a sufficient degree to provide a surface of flat or plane form and at a proper distance from the axis of the body member to receive the tool or plane bitK' The tool-clamping memoriiices 8, which plane surfaces are adapted to contact with the tools when the same are clamped in the tool-carrier. It is desirable that the tool-clamping member? 7 shall clampingly engage the tool near its cutting edge (i. e. adjacent the first recess 5) more tightly than said tool is thus engaged further back from its-cuttingedge, as toward the clamping bolts 9. To efiect this end, the tool-clamping members. are provided with rearward portions 13 adapted to abut against that side it of the second recess Gtwhich side is remote from the-tool; the inner surface otthe tool-clampingmembers at 15 engaging the tools near their cuttingiedges and the rearward abuttingportions13of the tool-clamping members. engaging the sides 1st of the second recesses :G'tightly under the action of the bolts, before such-bolts (located between said tightly engaging portions of the tool-clamping members) are turned sufliciently to press 'or-springithe plane surfaces 12 of said members into close engagement with the tools more rearwardly from their cutting edges. To provide for a proper formation of the rearward-portion of the tool'clamping member,-the edge of its said portion 13 (assuch member is first formed) desirably extends furtherurthan necessary to accomplish-the endabove described and is. thereafter cut or dressed down sufficiently to enable the. members 1 and 7 to securely.clamp-thetoolbetween them in the manner described.

This toolclampirig member 7 is .made in pairs by forming an elongated blank 20 (seen in Figure 3-) substantially circular in cross-section and with a longitudinally. disbeyondthe axis or the blank. The blank may then be severed longitudinally midway between the sides 22, 23 of said groove onthe line at in said figure. Such severing provides a pair of tool-clamping mem bers, whose rearward abutting edges may bolted-together condition the edge oi: the

rearward portion 13 of the toolclamping member 7 abuts against the side 14: of the recess 6. "The periphery of the entire toolcarrier is now out orturned down in a lathe to the desired diameter, such per1phe1'y when such turning operation is finished being shown at 26 in Figure 1. It will be seen that inasmuch as the filler piece is somewhat thicker than the tool to be used 'in'the tool- I carrier,'the tool-clamping member will more tightly clamp the toolnear its cutting edge than rea-rwardly therefrom when the tool is held between the members 1 and 7. The

' bodymember 1 may be "formed in initial or rough form to extend beyond lts finished pe 'riphery 26, such extensions being shown no dotted lines at 27 in Figure 1. Dotted arcuate lines 28 111 said figure illustrate the degrees to wh1ch the body member may be turned or dressed down to provide a tooicarrier of desired diameter; and dotted arcuate lines 29 in l igure'il illustrate degrees to which the tool-clamping member may be dressed or turned down tor the same purpose. The dotted lines 1n F1gure 1 lliustrate positions of the surface ofthe table portions 3 to which such portions may be cut or dressed to accommodate tools of greater thickness.

It will be seen that by my process or methodot making a tool-carrier, the members 1 and 7 as initially formed may be readily machined, turned or dresses down to desired degrees; and that such members as initially formed may be at any time readily modified or changed so as to form a toolcarrier of less diameter, or one adapted to tools of different thickness.

Suitable openings 40 are provided through which a tool may be thrust to adjust the position of the plane bits.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of the processes or methods hereinbefore set forth, further than as pointed out in the claims.

I claim:

1. The method of making a rotatable toolcarrier for a machine of the character described, which method consists in; forming an elongated body member with means at its ends for mounting the same rotatably, and with a table portion and first and second recesses adjacent the opposite sides respectively of the table portion; forming a tool-clamp ing member adapted to co-operate with the table portion adjacent the first recess to clamp the tool therebetween and having a portion adapted to abut in the tool-clamping position of said members against that side of the second recess which is remote from the tool; clamping said two members together in tool-clamping relation with a filler piece between them; and cutting down the periphery of said assembled two members in a lathe.

j 2. T he method of making a rotatable tool'- carrier for a machine ot-the' character described, whichmethod consists in; forming an elongatcd'body member with means at its ends for mounting the same rotatably, and with a. table portion and first and second recesses adjacent the opposite sides respectively of the table portion; forming a toolclamping member adapted to cooperate with the table portion adjacent the first recess to clamp the tool therebetween and having a portion adapted to abut in the tool-clamping position of said members against that side of the second recess which is remote from the tool; clamping said'two members together in tool-clamping relation with a filler piece thicker than the tool between them; and cuttingfl'down the periphery of said assembled two members in a lathe.

3;lhe method of making the elongated body member of a rotatable tool-carrier for a machine of the character described, which method consists in; rolling a metal blank lengthwise through a rolling mill to form thereon a table portion and longitudinally extending first and second recesses adj a-- cent the opposite sides respectively of the table portion; and dressing'down thesurface of the table portion.

t. The method of making a rotatable toolcarrier for a machine of the character described which method consists in; forming an elongated body member by rolling a metal blank lengthwise through a rolling mill to form thereon a table portion and longitudinally extending first and second recesses adjacent the opposite sides respectlvely of the table port1on; dressing down the'suritace of the table portion; forming a tool-clamping member adapted to co -operate with said table portionadjacent the first recess to clamp the tool'therebetween, and having a portion adapted to abut in the tool-clamping position of said members against that side of the second recess which isremote from'the -tool; and cutting down said abutting portion of the tool-clamping member sufficiently to enable said members to securely clamp the tool between them.

5. The method of making a pair of toolclamping members of a rotatable tool-carrier for a machine of? the character described, which method consists in; forming an elongated blank substantially circular in cross section and With a longitudinally disposed groove extending inwardly beyond the axis of the blank; and severing the blank longitudinally midway between the sides of said groove.
